Correction of Posttraumatic Aphakia in Children with Folding Lenses Sutured to the Iris

Abstract

Objective: To characterize visual outcomes of iris-sutured posterior chamber foldable intraocular lens implantation in traumatic aphakia in pediatric patients.

Methods: A pre-experimental, prospective, longitudinal, pre-experimental study was performed with 17 children, with a one-year follow-up. A complete ophthalmologic examination was performed and variables such as age, sex, laterality, best visual acuity without correction, with correction, refractive results, intraocular pressure and complications were evaluated.

Results: The average age was 13.2 years, 64.7% were male. The best visual acuity without correction preoperatively was 47.1 % <0.1 and with correction 0.7, one year postoperative visual acuity was 0.43/0.78, respectively. Preoperative intraocular pressure was 14.1 mm Hg, and at one year 14.71 mm Hg. Cell density preoperatively was 2559.76 cells/mm2 and at one year 2475.88 cells/mm2. The preoperative hexagonality was 53.12 % and at one year 56.94 %. Preoperative cylinder -1.35 D and 23.5 % presented induced astigmatism at one year postoperatively.

Conclusions: The application of posterior chamber foldable intraocular lens implant sutured to the iris in traumatic aphakia in pediatric patients achieves improved visual acuity and the most frequent complication was corneal edema.
